How is α-methylcinnamic acid (CAS: 1199-77-5) typically synthesized?

α-Methylcinnamic acid is typically synthesized by the reduction of cinnamic acid with sodium borohydride or lithium aluminum hydride. Another method involves the amide hydrolysis of α-methylcinnamic anhydride. The yield is typically around 70-80%, and the reaction is performed under anhydrous conditions to avoid side reactions. This compound is also used as an intermediate in the synthesis of fragrances and pharmaceuticals.
